    Notes: Two patients are reported with cutaneous malignant melanoma who had been on treatment with cyclosporin A. The first case was a 44-year-old man with systemic sclerosis and the second a 52-year-old woman who had a renal transplant. In both cases cyclosporin A was administered with a low dose of prednisone.

    Simple three-dimensional periodic orbits in a galactic-type potential (1985)

    Notes: Abstract We study the families of simple periodic orbits in a three-dimensional system that represents the inner parts of a perturbed triaxial galaxy. The perturbations depend on two control parameters. We find the regions where each family is stable, simply unstable, doubly unstable, or complex unstable. the stable and simply unstable families produce other families by bifurcation. Several families reach a maximum (or minimum) perturbation and then are continued by other families. The bifurcations are direct or inverse. The transition from one type of bifurcation to the other is theoretically explained. Another important phenomenon is the splitting of one family into two, or the joining of two families into one. We do not have any complex instability in the limiting cases of two-dimensional motions (when one control parameter is zero). The two main families of periodic orbits are in most cases stable when the energy is smaller than the escape energy. Most high energy orbits are unstable. However, we found stable orbits even for energies about four times larger than the escape energy.

    Notes: Abstract The 2∶2∶1-resonance case for a potential problem with three degrees of freedom is characterized by the existence of two isolating approximate integrals apart from the energy. This result completes a statement by Gustavson concerning the number of formal integrals in resonant Hamiltonian systems.

    Numerical study of periodic orbit properties in a dynamical system with three degrees of freedom (1982)

    Notes: Abstract The locations and stability features of the main symmetrical periodic orbits in the potential $$V = \tfrac{1}{2}\left( {Ax^2 + By^2 + Cz^2 } \right) - \varepsilon xz^2 - \eta yz^2 with \sqrt {A:} \sqrt {B:} \sqrt C = 6:4:3$$ are calculated. Two resonant 1-periodic orbits reveal themselves to be the most important of the system. The third dimension and the additional coupling term have a large effect upon the emergence and stability of p.o. prolongated from the bi-dimensional cases 4∶3 and 2∶1. The existence of three main instability types leads to behaviours much more complicated than in systems with two degrees of freedom. Particularly the presence of complex instability, a new feature with respect to bi-dimensional problems, may produce large instability regions in the set of initial conditions. Some asymptotic curves emanating from unstable orbits are calculated in the four-dimensional space of section. The aspect of such curves is considerably modified when a perturbation is added in the third dimension. The neighbourhood of orbits suffering from complex instability is studied in the space of section and by means of the maximum Lyapunov Characteristic Number technique. It is shown that the motion can deviate far from the vicinity of the p.o. representative point as soon as the orbit is of complex instability. When the perturbation is large enough, the stochasticity produced by this type of instability can be very important.

    Notes: Summary In one case of Dubin-Johnson Syndrom, the Authors call attention to the importance of mitochondrial alterations, which involve more than half of these organelles. These alterations are of 2 different types: the first one is a fibrillary degeneration, as previously published in many other cases, and the second a vacuolary degeneration of a new type. The hepatocyte also shows an alteration of its sinusoidal surface and an accumulation of biliary pigments.

    Notes: Summary 15 liver biopsies from 13 patients suffering from non-hemolytic constitutional jaundice (6 cases of Gilbert's, 2 cases of Rotor's and 5 cases of Dubin-Johnson's disease) provided the basis of an ultrastructural study of pigment inclusions in liver cells following various techniques of preparation. The lipofuscin in Gilbert's syndrom and the pigment characteristic of Dubin-Johnson's syndrom contain two distinct components which are present in both types of inclusions but their proportions are different in these syndromes: a globular component, probably of lipidic nature, is the main constituent of the lipofuscin, a granulo-filamentous component the main constituent of the Dubin-Johnson's pigment. These two components react in both syndromes identically to various techniques of fixation, embedding and section-staining. In Rotor's syndrome other pigment inclusions are observed which are not detectable in ordinary histological preparations: they consist essentially of aggregates of dense, ferritin-like material. The presence, in the hepatocytes, of pigment inclusions which have some features in common in the 3 types of syndromes and other characteristics specific for each of them, confirms the close relation between these types of jaundice, but emphasizes also their differences; moreover, this ultrastructural study underlines the difficulty of an exact classification of these syndromes.
